To all to/wm 'i1/Amay concern.'

Be it known that ll, @une L. GILLILAND, a citizen of the United States, residing at Ortl'ey, in the county of Roberts and State of South Dakota, have invented certain new and useful improvements in Shock-Loaders; and l do hereby declare the following to be a full, clear, and enact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved shock loader so-called, to-wit, a machine adapted to pick up shocks of grain, bundles of grain, or even loose grain and deposit the same in a receptacle preferably, awagon driven along at the side of the machine. Y

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

'llhe improved shock loader is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. l

Referring to the drawings, Figure 1 is a plan view of the machine, some parts thereof being removed; Fig. 1^ is a etail in section lon the line ma ma of Fig. 1; ig. 2 is a side elevation of the machine; Fig. 3 is a rear elevation of the machine; Figa is a vertical section taken onthe line at tot of Fig. 1, some parts being broken away; Fig. 5 is a transverse vertical section taken on the line a5 m5 of Fig. 1; Fig. 6 is a detail yin section taken on the line .r6 m ot Fig. 5; Fig. 7 is a plan view of one of the so-called bundle gathering devices, some parts being broken away; Fig. t3 is a sideelevation of thel parts shown in Fig. i', some parts being indicated by dotted lines; Fig. 9 is a diagrammatic detail showing certain driving connections found in the vicinity of the line marked te as on Fig. 1; Fig. is a diagrammatic detail illustrating driving connections shown in the vicinity of the line marked m10 am on Fig. 1; and Fig. 1l is a transverse section on the line .rf--m of Fig. 1, some parts being removed.

'llhe machine comprises a main truck' frame 1 and supplemental or gathering frames 2, the projecting front end side portions of the former being connected to the lrear end portions ot the lattery by hinges 3.

(See Figs. 2 and e.)

The main truck frame 1 is supported by rear traction wheels 4 andV front steering wheels The said traction wheels l are connected in the usual way to the ends of a rear axle 6 that is journaled in suitable bearings on the rear portion of the frame 1. rlhe steering wheels 5 are loosely 'ournaled on the ends of a relatively short ront axle 7 that 1s intermediately ivoted to an overlying short bolster 8 rigidly secured to the front portion of the said frame 1 rlhe supplemental or gathering frames 2.

are laterally spaced and extended vertically and longitudinally of the machine and their front end portions are carried on caster wheels 9 (see Figs. 2 and 8), The lower plates of the gathering frames 2 are tor Awardly extended and upwardly curved so that they will not catch in the ground even if brought into contact with irregular ground. The caster wheels 9 permit the front end portions of the gathering frames to follow the course of the machine with a little lateral resistance. l,

Working between the two laterally spaced forwardly projecting gathering frames 2`is a gathering deck preferably in the form ot a fork or slatted structure 10, which, at its rear end portion, is pivotally connected to the laterally spaced forwardly projecting portions of the main frame 1, by a transverse hinge slot 11 (see Figs. 1, 2 and d). At its rear end portion, the fork 10 is provided with rearwardly and upwardly proj ecting laterally spaced lifting arms 12, the ends of which are attached to the front ends of fork lifting cables 13. IFliese cables 13, as shown, pass under idle guide sheaves 1t mounted on a transverse rodv 15 `secured to the main frame 1. rlfhe rear ends of the said cables 13 are attached to and adapted to be wound upon small windlass drums 16 secured to a transverse windlass shaft 17 journale'd in suitable bearings 18 as shown, secured on a rearwardly projecting operators platform 19 which, in turn, is rigidly secured. to the mai-n frame l. When the cables 13 are drawn upon, the front end of the gathering fork 10 will be raised, and conversely, when the cables are slackened, the front end of the said fork will be lowered into position to pick up from the ground, shocks, or bundles of grain or even loose grain. For holding the fork in an inoperative position, au ordinary latch segment 20 'Iii Bti

Oli

(see Figs. 1 and 3) is secured to one of the bearings 18, and the windless shaft 17 is provided with a latch lever 21 for coperation of the said segment.

Journaled in each gatheringv frame 2 at the front and rear thereof are approximately vertical sprocket shafts 22 that carry upper and lower sprockets 23. Sprocket chains 24 run over the .coperating upper and lower sprockets 23.and these sprocket chains carry outwardly projecting approximately Vertical gatheringblades 25 that are braced from the links thereof so that they will always stand approximately at the right angle to the links to which they are attached. As shown in Figs. 7 and 8, the gathering blades 2.5 are pivotally attached at their inner edges to vertical slats 26 secured to certain of the vflanges of the upper and lower coperating chains 23, and to brace the same without destroying the flexibility of lsaid chains, oblique upper .and lower bracing linksy 27'are pivoted to the said `blades 25 and the adjacent slats 28 secured to other links of said `upper and lower coperating chains. The lower ends of the rear sprocket shafts 22 carry beveled gears 29 that mesh with beveled gears 30 carried by short approximately horizontal shafts 31 journaled in suitable bearings 32 secured on the bottom of the gathering frames 2. The rear ends of these short 4 shafts 31 are connected by knuckle joints 33 to the front ends of driving shafts 34 vjournaled in suitable bearings on the frame 1 and provided at the rear ends with beveled gears 35 (see Figs. 1 and 2). The vbeveled gears 35 mesh with bevel gears 36 carried by the outer ends of the transverse shaft 37 journaled in suitable bearings on the frame l. At its intermediate portion, the trans-` verse shaft 37 is provided with a sprocket 38 (see Figs.v 1 and "4) over which and a larger sprocket 39 on the rear axle 6 runs Vma a sprocket chain 40. The sprocket 39 is loosely journaled on the rear axle 6 but is held against lateralmovements and carries a half clutch 42 (see particularly Figs. 1 and 5). The half clutch 42 is adapted to be engaged by a coperating half clutch 41 that is mounted to slide'u on but is carried with the rear axle 6. T e engagement of the half clutch 41 with the half clutch 42 and the disengagement therefrom, so as,

to couple :the axle 6 to the shaft 37 and to disconnect the same therefrom, at will, is as shown, accomplished by means of a shipper lever 43 (see Figs. 1 and 6), which is intermediately pivoted to a transverse bar of the main frame 1 with its free end workingin a groove of the half clutch 41.

xtending rearward and slightly upward from the gathering fork 10 with its lower front portlon positloned `to receive from the rear portion of the said fork, is an endless slat and belt conveyer, as shown, made up of sprocket chains 44 and toothed slats 45. These chains 44 run over small sprockets 46 (see Figs'l and 4) carried by transverse shafts 47 .mounted in suitable bearings on the projecting side portions of the main frame 1. The upper shaft 47 projects at one end and is provided with a'sprocket 48 (see Figs. 1`and 9). A sprocket chain 49 runs over the sprocket 48 and over a sprocket 50 on a transverse countershaft 51 journaled in suitable bearings on the frame 1. The counter shaft 51 is provided with a spur gear 52 that meshes with the spur gear 53 carried by the counter shaft 37, already noted. r1`he shaft 51 and connections between the same and the shafts 37 and 47 serve todrive the inclined carrier belt 44-745 in the proper direction.

Side boards 54 are, as shown, rigidly secured to the oblique side bars 1 of t-he frame 1 just outside of the carrier or conveyer belt. 44-45 Also it may be here noted that the elevator shafts or rollers 47 are journaled in the ends of these oblique bars 1B. The endless conveyer 44-45 projects over and is arranged to deliver the bundles or grain onto the receiving portion of a transversely extended and movable endless elevator belt shown, as preferred, as made of endless sprocket chains 55 and transverse toothed slides 56 (see particularly Figs. 1 and 5). That portion of the elevator belt which extends across the rear portion of the machine frame 1 is horizontally disposed and that portion thereof which pro jects at one side of the said frame is obliquely extended upward, preferably at an angle of about 30 degrees. At its receiving and delivery portions, respectively, the sprocket chain 55 runs over small sprockets 57 and 58 of sprocket shafts 59-60. The

shaft 59 is journaled in suitable bearings on a superstructure 1b formed as part of the rear portion of the frame 1 and supporting a transverse stop board 61 at the rear of the horizontal portion of the said elevator belt 55-56. The shaft 60 is journaled in suitable bearings on the upper end port-ion of an oblique frame extension 62, the

' front and rear sides of which project high above said elevator belt so as to confine the bundles and hold the same subject to the said elevator belt. This frame extension 62, at its lower'end, is rigidly secured to the frame superstructure 1". The intermediate lower runs of the chains 55 run under idle 'guideA sprockets 63 of an idle shaft 64 (see Figs. l, 4 and 5), journaled in suitable bearings on the frame superstructure 1". The intermediate portions of the upper runs of the said chains 55 run under idle guide wheels 65 journaled" to longitudinally spaced upwardly extended portions of the frame superstructure 1b.

novanta rlfhe sprocket shaft 58, Vat its front end is` provided with a sprocket 66 and the intermediate sprocket shaft (i4 is provided at its front end with two sprockets 67-68. The sprocket chain 69 runs over the sprockets (i6-67. A short sprocket chain 70 runs over the sprocket (i8 and over a sprocket 71; carried by a counter shaft 72 journaled in suitable bearings on the frame 1. At itsE front end, the shaft 72 is provided with a small beveled gear 73 that meshes with a bevel gear' 74 `carried by the shaft 37, be-I fore noted, (see Figs. 1 and 10). rvll`hese connections serve to drive the elevator belt; in the proper direction from the counter: shaft 37. y

The machine is steered by manipulation? of a hand wheel 75 secured to the upper end of a steering post 7G (see Figs. 1, 2 and 3), mounted in suitable bearings on the frame 1 and superstructure 1b and provided at its lower end with a worm 77. llhe worm 77 engages a'worm gean 78 secured on the rear end of the rod 79 mounted in suitable bearings on the frame structure 1. At its front end, the shaft 79 is provided with a worm 80 that meshes with a worm gear 81 secured on one end of a short windlass shaft 82 (see Fig. 1) mounted in suitable bearings on the frame 1. The shaft 82 carries a windlass drum 83. A. steering cable 84 vis secured to and wound upon the drum 83,

and its ends are attached to the front axle 7 at points on opposite sides of its pivotal connection to the bolster 8.

. The side members of the gathering fork or deck 10, to which the lifting arms 12 are secured, see Figs. 1 and 1a are provided with outwardly extended yokes 12a that embrace adjacent parallel bars al, the front endsof which are rigidly secured to the base or lower portionsof the gathering frames 2. rllhese yokes permit the required'limited vertical movements of the gathering fork and cause the fork to serve as a brace to tie the gathering frames together against lateral separation.

ln the main views of the drawings, the gathering frames are shown as set in vertical positions and they are operative in such po-I sitions, but preferably, they are inclined inward toward their tops, as shown in Fig. 11, by reference to which,l it will be noted, thatl vthe gathering plates or arms 25 are set at such angles m respect to the inclined gathering frames thatthey will be horizontally disposed when moved .over the gathering fork 12. l/Vhen the gathering plates 25 are moved at the rear of the gathering frames and backward along their-outer sides, they are turned upward at steep angles, so that they will readily clear the various other` parts of the machine.

This improved machine may be propelled or driven forward .either by an explosive engine carried on the framework thereof, and having suitable connections to the rear axle or in any other transverse shaft, or it may be drawn by horses attached thereto in any of the well knownv ways.

Under forward movement of they machine, the shocks, bundles `or loose grain will be picked up by the fork and will be forced rearward on the said fork by the alternate actions of the gathering blades Ior larms of the gathering heads and will be delivered to the receiving lower portion of the endless inclined carrier l14'--45. By the latter, they will be delivered onto the horizontal receiving portion of the elevator belt -56 and by this elevator belt will be raised and then dropped onto the wagon or receptacle which 1s moved at the side of the machine. When the machine is out of action and simply driven or moved from place to place, the,

Vfork may be raised by manipulation of the lever 21, and all the running parts of the machine thrown out of action by manipulation of the shipper lever 43.
